Solved Yuki, two different solutions to this one.
Also like Gomen a lot, not just the design, but also the shortage of builders that forces you to make use of good timing instead of entirely blocking off the crowd.
Attached is the latest version of Don't catch me.
I also had a go at fixing Broadway, it should eliminate the known backroutes, while my solution still works. You said your solution is slightly different, so I'm not sure whether that one works as well (I also cut down one walker, but that can be added again), and I don't know whether I've introduced some new backroutes somehow either.
